Hi,

I have linux server in a network that I cannot acces from outside. I create an autossh from those server to a Web Linux Box.

I' connecting to the Web linux box, and do a ssh root@localhost -p 6666 (6666 is the port I use for reverse ssh)

On inside server in rc.local I have : autossh -M 10984 -N -f -o "PubkeyAuthentication=yes" -o "PasswordAuthentication=no" -i /root/.ssh/nopwd -R 6666:localhost:22 root@WEB-LINUX-Box -p 22 &

In Web Box I can do : ssh root@localhost -p 6666


But the thing is, I want to use my web browser to access web service into Inside linux Box. How can I do reverse SOCKS Proxy in this case?

Regards,

JEAN

Good morning,

I have been naded an unusual issue, at least in my experience.

We have extremely important emails being sent from the UK via an MPLS setup, and they are using Private DNS entries. Our SPam and Email servers require rDNS or the emails are blocked. We whitelisted and IP address for them yesterday but that did not seem to help.

This has been escalated to top priority as these emails are for our CEO and COO. What can I do from my end to ensure that the emails can be received and delievered?

I have about four hours to correct this as the senders are on UK time and I am on EST time, so if anyne can help me I would be most gratefull.

Thanks
Matt

I have a VPN being created in my domain environment that I cannot find to disable. Inherited the environment from the previous team, and there is no documentation. Where can I look? I scoured the three group policies that are being applied to my computer and there is nothing there I could find.

Hi,

I have a connection issue to my openvpn (Synology) on Windows, but same config works fine on Android.
On server itself I don't find any log indicating what is going on.

We just started using a VPN.  When I entered the information for the VPN I now get the message "Working Offline" and I can no longer send/retrieve email.  I use Outlook 2010 https://outlook.office365.com/mapi/emsmd.

How do I fix this?  I run my entire life out of Outlook.  It syncs to my Android phone:  keeps all of my appointments, contacts, and email.  If I cannot access these things on my computer and still need to sync with my phone.

Hi,
I setup a MAC user to use VPN for accessing company file shares. She was able to do this fine when she was in London.
She's traveled to Australia and tried VPN there. The VPN connects fine but she cannot access the file shares. Her accounts are all fine.
They try to connect but fail. The file shares are using the UNC path but with the IP address so example - \\ipaddress\sharename
Is it because the connection to the file shares is timing out due to the distance?
Can I increase the timeout settings on a MAC for accessing network shares

Hi,
I have a windows 10 computer and I'm using Offline Sync Files so that my network files are available to me all the time.
When I connect using VPN, I have access to all files except those included in the Sync process.
Windows seems to not get that I am not connected to the network and have access to all File Servers, and I don't see a "Force Retry Connection" button anywhere.... how can I make it realise I am not "away" anymore...?

When a user log onto domain, where can I find which DC authenticated through kerberos in DC event log?
I see only the user IP, workstation hostname, user name, but no DC information?
from client, I can issue %logonserver% or nltest /dsgetdc:sea. But I need to get a report what DC authenticated who. How can I update this information?

Also, if the user is home office user through VPN, it doesn't seem the logon event is even being recorded in DC's security event log.
For VPN users, how can I trace which DC authenticate which user?

DC: Windows Server 2012

In SBS 2008 (and 2011) the maximum number of concurrent VPN users is set at 5 out of the box. You have to make a change in the Routing and Remote Access console to increase the number allowed.

Not sure if a similar limitation exists in Server 2016 Standard with Essentials Role. With bad weather today in NJ I have most clients working from home. One has 21 users Logged into VPN. No issues, but I'm just trying to find out if there is any limitation on the number of concurrent VPN connections in 2016 (and how it can be increased) - just in case...

Anyone know?

I recently installed a Cisco 1921 router as the def gateway for my network. I also have a Cisco ASA5505 9.2 on the LAN behind the router. My goal is to allow AnyConnect Client SSL, Clientless SSL and site to site VPN passthrough on the router. So far I had a chance to test Client SSL and Clientless SSL and my router configuration does not seem to be working. From the LAN I can establish a VPN session to the outside interface of the ASA. Can you please review my configuration and point me in the right direction?

I have a user who has a laptop that is joined to the companies internal windows server 2012 r2 domain.

He has network drives mapped via a login script. These work fine internally but when connected via VPN (using the Draytek Smart VPN client) the drives do not work. I know that this is casued by the DNS servers being unable to resolve to the fileserver name on the company network.

The user is currently using the cached domain account to log into the laptop whilst off the company network.

We are curently using the Draytek router as a VPN server.

Can someone tell me the best way to make the user experience when connected via VPN as smooth as possible for the end user.

Dear Experts

I m a Private Internet Access VPN user. I have another Linux laptop working fine with the VPN tunnel.

With Parrot VPN version 3.10 I m not able to get the tunnel to work. Not even OpenVPN is working.

The PIA app shows installed it is just not running.

I wonder if there is some permission I need to work here?

Please advice

Thank you
